several L2L ipsec VPN to the same destination (ip address)

• Multiple VPNS to the same destination

  Greetings,

  I have a pair of ASA5510 used to complete LAN - LAN VPN IPSec (active-standby) using static routing.  I have a business partner who wants to have a primary and a VPN failover (it has 2 different end points) so I understand I have to configure different VPN 2.

  My problem is with the routing.  How can I get the traffic to use the primary link all the time and only make it appear the secondary image when the primary fails?  And tipping back in elementary school when it is restored?

  Weighted roads were mentioned (does not cover restoration), but the destination is the same in both cases (the next hop is the external gateway address).

  Thanks heaps.

  Reece.

  Hey Reece,

  You can use the crypto map command to add the two IP addresses in the remote end:

  "card crypto <#> peer set."

  The ASA will try to negotiate with peers "x.x.x.x".

  If "x.x.x.x" has failed or is not responding, it will try to negotiate with "y.y.y.y".

  Let me know if that helps!

• A Site to remote access VPN behind the same public IP address

  Got a problem quite stupid.  We have a VPN from Site to Site configured for a new data center, which will be responsible for general traffic management.  In addition, some users need to use use a VPN client to access certain areas.  The firewall at the Office only has a public IP address, so the two will come to the Site to Site VPN for remote access from the same source.

  This seems a problem with legacy Cisco VPN clients because encryption card matches the entry VPN site-to-site, even if they use VPN clients.  A good/simple solution to solve this problem?

  Some newspapers (198.18.85.23) is the address public IP for the office and the tom.jones is the user.  192.168.1.0/24 is the pool of the VPN client.

  Hello

  Don't know if this will work, but you can try the following configuration (with the rest of the VPN configuration)

  list-access CLIENT VPN ip enable any 192.168.1.0 255.255.255.0

  card crypto OUTSIDE_map 4 is the VPN CLIENT address

  card crypto OUTSIDE_map 4 set peer 198.18.85.23

  card crypto OUTSIDE_map 4 set ikev1 transform-set ESP-AES-128-SHA ESP-3DES-SHA

  The idea would be to have the ACL matches the VPN full Tunnel that the Client attempts to establish. (destination "any" from the point of view of the customer, the ASAs view source)

  I tested briefly on my own SAA by connecting from an IP address to which the ASA offers free VPN in L2L. But as I don't have the operational L2L VPN, I can't really verify the VPN L2L at the moment. Thus, certain risks may be involved if you can afford it.

• PIX 7 - several remote VPN sessions to the same public IP address

  Hello

  Here's my problem:

  Employee A and employee B make VPN connections to the PIX even with their Cisco VPN clients. The two employees are behind the same NAT device, so have the same public IP address.

  As soon as the second employee initiates the VPN connection, the first employee is disconnected.

  I have a similar situation with a PIX 6.x version and it does not. Two employees can connect at the same time with the same credentials.

  Here is the configuration of remote access VPN I use:

  attributes of the strategy group gpolicy

  VPN - 5 concurrent connections

  Protocol-tunnel-VPN IPSec

  enable IPSec-udp

• 2 for the same destination vpn tunnels

  Hi all

  It is posibble on my asa to create 2 stay for the same destination device vpn tunnels?

  see you soon

  Carl

  You can not have 2 vpn tunnels going to the same destination device.

  However, you can have card crypto with counterpart set going 2 ip addresses of peers.

  Example:

  map mymap 30 set peer 1.1.1.1 crypto 2.2.2.2

  There was a problem creating the destination folder. If please check the permission of folder or choose a different folder.   What that means, tried to name several different folders, but still the same error message. Would be grateful for the help!

  This means that the folder you want to create is blocked because of file permissions. The drive or folder you are trying to create the destination folder is set to read-only, and your username does not have write permissions.

• IPSEC VPN on the dual WAN links

  Thank you

  Jesse,

  One of the solutions to your problem is to apply the same for both interfaces crypto card and have the two counterparts mentioned under a crypto map entry.

  Since you're using track/IP SLA to activate a single link to a single IP address of time will be answers.

  http://www.Cisco.com/en/us/docs/security/ASA/asa84/command/reference/C5.html#wp2278871

  Have several inputs card crypto with the same statement in game will cause problems.

  Hope that makes sense.

• You try to run a Site to site VPN and remote VPN from the same IP remotely

  We currently have a site to site VPN configuration between our offices call center and a 3rd party that allows them to access our training to their employees to use environment while being trained on our systems. This tunnel is running between our ASA and their ASA without problem; However, when we have managers come out to the call center, they are unable to use remote VPN to access our office.

  Apparently the same IP peer remote that we use for our site to the other tunnel is the same IP that our managers use to access the internet when they are on-site with the customer. When I look at the logs it shows the VPN attempt and then I get treatment Information Exchange has failed. So from what I can understand when our managers are trying to connect to our firewall from the same IP address as the counterpart of site to site it automatically tries to create a tunnel, according to the information of the site to the other tunnel. If our managers are anywhere else, they can connect through remote VPN with no problems.

  My question is if anyone knows of a way to make the firewall allow VPN site to site and remote connections with the same remote IP address.

  Hi John,.

  Basically, in older versions, when you hit a static encryption card and you does not match this static encryption completely map the connection continues until the dynamic encryption card. For this reason, you can connect your IPSec clients before. A bug has been opened on this vulnerability.

  CSCuc75090  Details of bug

  The crypto IPSec Security Association are created by dynamic crypto map to static peers

  Symptom:

  When a static VPN peer adds all traffic to the ACL crypto, a surveillance society is based even if the pair IP is not allowed in the acl to the main façade encryption. Are these SA finally put in correspondence and commissioning the dynamic crypto map instance.

  Conditions:

  It was a planned design since the first day that allowed customers to fall through in the case of static crypto map did not provide a necessary cryptographic services.

  The SA must be made from a peer configured statically and a dynamic crypto map instance must be configured on the receiving end.

  Workaround solution:

  N/A

  Some possible workarounds are:

  Configure a static nat device when you try to use the remote VPN if the firewall remotely will be hit with a different public IP address. It would be a good solution, but it will depend on how many ip addresses public you have available, if you really want one of these ip addresses for that access.

  Also, I thought you could use AnyConnect instead of the IPSec VPN client. I don't know how many users need to connect from your PC to the remote site, but the ASA has 2 licenses SSL available that you could use. Because Anyconnect uses the SSL protocol, it won't have a problem on your environment.

  Below some information:

  http://www.Cisco.com/c/en/us/TD/docs/security/ASA/asa84/configuration/guide/asa_84_cli_config/vpn_anyconnect.html

  Hope this helps,

  Luis.

  Hello guys,.

  I have Cisco ASA5520 facing the ISP with private IP address. We don't have a router and how to get the IPSec VPN through the internet?

  The question statement not the interface pointing to ISP isn't IP address private and inside as well.

  Firewall configuration:

  Firewall outside interface Gi0 10.0.1.2 > ISP 10.0.1.1 with security-level 0

  Firewall inside the interface Ethernet0 192.168.1.1 > LAN switch 192.168.1.2 with security-level 100

  I have public IP block 199.9.9.1/28

  How can I use the public IP address to create the IPSec VPN tunnel between two sites across the internet?

  can I assign a public IP address on the Gig1 inside the interface with the security level of 100 and how to apply inside to carry on this interface?

  If I configure > firewall inside of the item in gi1 interface ip address 199.9.9.1/28 with security-level 100. How to make a safe lane VPN through this interface on the internet?

  I'm used to the public IP address allocation to the interface outside of the firewall and private inside the interface IP address.

  Please help with configuration examples and advise.

  Thank you

  Eric

  Unfortunately, you can only complete the VPN connection on the interface the VPN connection source, in your case the external interface.

  3 options:

  (1) connect a router in front of the ASA and assign your public ip address to the ASA outside interface.

  OR /.

  (2) If your ISP can perform static translation of 1 to 1, then you can always finish the VPN on the external interface and ask your provider what is the static ip address assigned to your ASA out of the IP (10.0.1.2) - this will launch the VPN of bidirectionally

  OR /.

  (3) If your ISP performs PAT (dynamic NAT), then you can only start the tunnel VPN on the side of the ASA and the other end of the tunnel must be configured to allow VPN LAN-to-LAN dynamics.

• I created a PDF form with several drop downs, all with the same drop-down values. When I select a value of 1 in the drop-down list fields, it breeds in all others - which I don't want. How can I fix?

  I created a PDF form with several drop downs, all with the same drop-down values. When I select a value of 1 in the drop-down list fields, it breeds in all others - which I don't want. Can I fix?

  I am fairly new to this, but I think it has to do with the way you have drop them downs named. Copy you a then keep stick in each area? If so, that's the problem. You must rename each with a different number: Dropdown1, Dropdown2, etc. I think this might solve the problem.

  Is it possible that several people can work on the same folio?

  I usually work with a friend on my folios. We have been working directly for a dropbox folder, and together have created us a user with the same name on our macs. This gives the same path to the file, so we can never be reprinted when we work together for this user account. Works very well.
